RELATED APPLICATIONS

This patent application claims the benefit of and priority to US Provisional Patent Application 62/808,438 filed Feb. 21, 2019, which is incorporated by reference herein.

BACKGROUND

Flat pack furniture is a well-known form of furniture that requires customer assembly. For example, U.S. Pat. No. 1,824,243 entitled Knock-down Furniture Structure was issued Sep. 22, 1931.

Also known as ready-to-assemble furniture, the separate components are packed in cartons which also contain assembly instructions. The furniture is generally simple to assemble with basic tools such as screwdrivers, which are also sometimes included.

More recently, flat pack building structures are designed in which wall and roof components are stacked and packaged for shipping. After such a flat pack building structure is received on site, it must be unpackaged then each of the wall and roof components are placed on a foundation and assembled. Assembly of such building structures is less time consuming then building a structure from scratch. Once assembled, such a building structures cannot be dissembled and then moved to another location.

Typically, intermodal shipping containers can typically be disassembled to be shipped back in a flat format to save space on freighters. In some cases, the one of the side walls of the container may fold inward, however, the top panel must first be removed, which may require a crane. The same goes for re-assembly, a crane maybe needed to install the top panel. There have attempts to repurpose such intermodal shipping containers for portable buildings. Since the containers are built out of 4 tons of steel, cranes are needed to move and rebuild the containers and outer surface configurations are fixed do to the steel sides.

New systems and methods are thus needed which overcome these limitations. Various desirable features and characteristics will also become apparent from the subsequent detailed description and the claims, taken in conjunction with the accompanying drawings and this background section.

SUMMARY

Various embodiments provide a flat pack structure, which can be a foldable building system. The foldable building system is configured to move between a folded configuration to a built configuration without disassembling any of the side walls from the base or disassembling the roof panels from the side walls. In addition, the foldable building system is configured to move between a built configuration to a folded configuration without disassembling any of the side walls from the base or disassembling the roof panels from the side walls.

Various embodiments provide methods of use of a foldable building system. Moving from a built foldable building system to a folded configuration, a method can include the steps of folding a side wall in onto a base then rotating an attached roof panel and placing the roof panel on top of the side wall. The method can further include the steps of folding an opposite side wall onto the roof panel then rotating an attached opposite roof panel and placing the opposite roof panel on top of the opposite side wall.

Moving from a folded foldable building system to the built configuration, a method can include the steps of unfolding a side wall and attached roof panel and placing the side wall perpendicular to a base, then unfolding an opposite side wall and attached opposite roof panel and placing the opposite side wall perpendicular to the base. The method can further include the steps of rotating the roof panel toward a center point of the structure then rotating the opposite roof panel toward the center point of the structure and connecting the roof panel and the opposite roof panel at a peak of the structure. In some variations, the method can include the steps of locking the side wall and the opposite side wall orthogonally to the base.

FIG. 29 illustrates the details of the corner wrapper 310 in Circle C of FIG. 28.

Finally, FIG. 30 illustrates an application of the foldable building system as a greenhouse. Foldable greenhouse 400 comprises the structure of the foldable building system 100 or foldable building structure 200, as described herein. Foldable greenhouse further comprises a plurality of clear sheathing 402 encasing the foldable building structure. The clear sheathing 402 can comprise a door (not shown) and various openings configured as vents or utility feeds (also not shown). In some embodiments, the clear sheathing 402 is polycarbonate.

In some applications, the roof structure includes moveable vent panels (not shown). The moveable vent panels can be manually opened or opened with a motor. The moveable vent panels can be automated to open based on a timer and/or based on humidity.

In FIG. 30, the foldable greenhouse 400 is shown in a built configuration, which is encased with a clear sheathing 402. Further, the foldable greenhouse 400 contains plants 404. The greenhouse 400 comprising the plants 404 can be lifted by a forklift onto a flatbed trailer 405 to be transported to a different location without removing the plants 404.

In some applications, the foldable building system can be encased with solid panels. These solid panels will be configured as a totally solid panel, a panel with a window, a panel with a door or combinations thereof. All panels can have the same dimensions and can be easily interchanged. The panels can be constructed of a sheet metal skin, which can include insulated backing to meet environmental demands. The foldable building structure can be configured with plumbing, electrical features, HVAC, enhanced flooring, and combinations thereof.

In another application the foldable building system can be configured as a guard shack. For example, the foldable building structure can be encased with panels comprising ballistic protection. This ballistic protection could take several forms. One option could utilize a plaster-like substance called BallisiCrete that is applied on site. BallisiCrete has ceramic like strength and hardness qualities that are designed to stop all handgun bullets and most rifle bullets, even armor piercing. Another option could utilize a type of high-tech fiber with advanced polymers that creates an engineered fabric that provides strength and energy absorption. The process involves laminating multiple fiber layers in an engineered construction. Still another option could be a type of metallic type ballistic protection commonly used by our military, such as high hard steel.

In some applications, multiple foldable building structures can be connected to each other to form a larger structure. For example, four building structures can be connected in a rectangle. In such a configuration, the cross beams of the interior walls are not included, and interior space is encumbered a single post, which is the intersection of the four building structures. In another example, multiple foldable building structures can be laid out in a hamster configuration, which comprises groups of the building structures set up as larger rooms that are connected one of more of the building structures set linearly to operate all hallways between the larger rooms. Of course, any number of foldable building structures can set in any configuration, as needed by any application.
